酸素の透過を許し、内容商品の劣化を起すことが
ある。 It is as follows. That is, as mentioned above, the bottle cap is made of synthetic resin and has gas permeability, so if it is fitted onto the mouth of a bottle containing a product and displayed in a store for a long period of time, it will not absorb air in the air. Allows oxygen to pass through, which may cause deterioration of the product.
